Chapter 1 General Troubleshooting
1.4 Using CTC Diagnostics
Symptom There is a BBE TCA on all transponders that the OCH passes through a single OTS section.
Possible Cause This is not a transponder or channel-related issue.
Recommended Action The problem is in the intercabinet signal path preceding the transponder. Refer
to the Cisco ONS 15454 DWDM Procedure Guide for more information about configurations and
acceptance tests for this area.
Symptom You have a laser bias current (LBC) TCA on a single transponder.
Possible Cause The laser of the transponder is degrading.
Recommended Action The problem is within the laser circuitry. Check the OPT-PRE or OPT-BST
optical amplifier cards. Refer to the Cisco ONS 15454 DWDM Procedure Guide for more
information about setting up these cards.
1.4 Using CTC Diagnostics
In Software Release 7.0, CTC provides diagnostics for the following functions:
• Verifying proper card application-specific integrated circuit (ASIC) functionality
• Verifying standby card operation
• Verifying proper card LED operation
• Diagnostic circuit creation
• Customer problem notifications detected by alarms
• Provision of a downloadable, machine-readable diagnostic information file to be used by Cisco
Technical Support
Some of these functions, such as ASIC verification and standby card operation, are invisibly monitored
in background functions. Change or problem notifications are provided in the Alarms and Conditions
windows. Other diagnostic functions—verifying card LED function, creating bidirectional diagnostic
circuits, and also downloading diagnostic files for technical support—are available to the user in the
node view (single-shelf mode) or shelf view (multishelf mode) Maintenance > Diagnostic tab. The
user-operated diagnostic features are described in the following paragraphs.
1.4.1 Card LED Lamp Tests
A card LED lamp test determines whether card-level indication LEDs are operational. This diagnostic
test is run as part of the initial ONS 15454 turn-up, during maintenance routines, or any time you
question whether an LED is in working order. Maintenance or higher-level users can complete the
following tasks to verify LED operation.
Verify Card LED Operation
Step 1 In node view (single-shelf mode) or shelf view (multishelf mode), click the Maintenance > Diagnostic tabs
(Figure 1-15).
